DC current for an approximate temperature change of 40 C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, air-flow and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 125 C under worst case operating conditions verified in the end Peak current for approximately 30% Values @ 20 C5. Applied Volt-Time product (V- s) across the inductor. This value represents the applied V- s at 300 KHz neccessary to generate a core loss equal to 10% of the total losses for 40 C temperature mmPackaging information (mm)Supplied in tape and reel packaging, 130 parts per 13 + + + direction of feedSECTION VIEWTOP VIEWSCHEMATICRECOMMENDED PCB PAD LAYOUTHC2LP-xxxwwllyy R12xxx = Inductance valuewwllyy = Date code R = Revision level3 Technical Data 4114 Effective October 2015HC2 LPLow profile , high current power inductors lossIRMS DERATING WITH CORE LOSS100080060050040030020010080605040302 010%of Applied Volt- -Seconds99989796959492908070605040200%of LossesfromIrms(maximum)1 MHz500 KHz300 KHz200 KHz100 KHzOCL vs.
